max Zs please

[maccarooni]

I'm looking for the max zs on a 5s discon on a bs1361 fuse rated at 40A.

My BRB only gives me 30 and 45A figures.

Any ideas.

Also the Current carrying capacity on these fuses. am i right in 16.5kA.

as far as i can see on the certificate pads, brb and also on site guide i can only see the above 30 amp and 45 amp so i dont reckon theres a 40 A made in bs1361

I definetly removed it from the switch fuse and it said 40A (I'm sure). will be back there tomorrow and double check.

Thanks.

are all the 1361 rated at 16.5Ka ?

Are you sure it wasn't a BS88?

That would be 1.35ohms.

no definetly at 1361.

Rang NIC tec and asked their advice, they said " note it as calculation on cert..."

OK then.

it was marked up with 1971, which i presume is the year of manufacture.
